Hello nice video, But you don't show how to "USE" sync group/markers, you just show how to "CREATE" them... I already knew all of that, it's the very basics... What we all want to know is how to really "USE" them, where and how to tell unreal to USE created markers for the beginning of a transition in a blendspace?...
@@Frerducayou thanks for your comment! Have you watched that section? ua-cam.com/video/lWRsPl_IX7c/v-deo.html It might describe what you're referring to
@@MattCourtoisAnimYes I did, but you just show how to make sync groups in that section, you don't show how to make the sync happens? Are you saying that, just putting, same names, sync markers in 2 animations and then putting them in the same sync group will automatically make Unreal sync them? Without doing anything else??
@@MattCourtoisAnim I think it's just working I just tried out on my blendspace, just putting markers with same names and putting the animation in the same sync group, and it seems to work. I was confused I thought there was something else to do for telling Unreal how to use the markers in a blendspace/animBP but looks like we don't 😁 I got it now, Thanks😀
Most beginners might not get this as a helpful tutorial, But trust me this is a really helpful one. When you're in the polishing stage of your game, you need this type of advanced concept. Thanks for the detailed explanation and keep up the good work.
Ran across this with a weird blend issue between my run and sprint animation and shelved that problem for later. At the moment I wasn't even looking for a solution, but I'm super happy to find this tutorial vid explaining the solution. Nice one!
I can't believe I found this exactly a year (to the day) since the day you made this. This is EXACTLY what I was looking for as I couldn't find a clear enough explanation of the sync notifiers and sync groups.
This is amazing!!!! I love that you explained what was happening in unreal with drawings, I did a tweet about this a few weeks back because it happened to me in Unity but in Unreal I didn't found anyone talking about it, thank you so much!!!
Thanks a lot for sharing your thoughts and for your support. I'm glad it was helpful. Be sure to stick around for more, and to spread the word, I'd be extremely grateful!
@@MattCourtoisAnim this is really helpful, I don't have much reach but I retwitted your post there, a lot of animators will love to find out about this, I'm here to stay 🤣🤣
Hi mate, I am an animator with long experience in mobu, maya, max, and also worked for ubi. switched to unreal a while ago and came across your videos. I'm glad you share these videos they are very helpful and well done. looking for help on a proper blend between walk and idle - I need info on how and where to put the leg markers on the last step of walking, so that the legs don't slide while stopping in idle position, or when starting from an idle position to don't slide. So I found this video of yours. It's good, but not exactly what I was looking for. I ll keep searching and reading... if you find time to make a video about the other blends and transitions I'd be very grateful! Be alive and healthy!
Sync markers won't really help in your situation. What you would have to do instead, is to set two different flags during your walk cycle. They would tell what leg is currently in motion (ie you would typically set something like IsLeftLegMoving between a left step and a right step). You would have to have two different stop animations: one with the left leg up, the other with the right leg up, and then trigger one or the other depending on which flag is active. Does that make sense?
Does it work with blend spaces? because I have 2 states with similar blend spaces, got the same notifies, same sync group, but when transitioning it always start at the same position, instead of the matching one.
Sounds like something I miss in UE4, namely bone masks blending. But Blend Profiles seem to be dedicated to state machine transitions. Interesting... I'll investigate! Thanks man!
Awesome tutorial would love if you cover the start and stop animation without rootmotion am trying to do in my project so far I cant seem to get it right without sliding
Thanks a bunch man! No sliding without root motion is a tricky one, but it might be somewhat solvable using Animation Curves to drive the character speed. I haven't got a chance to look into them yet though.
Hello, Matt. Thanks for such a good explanation, probably the only video on youtube which covers sync groups in detail. Should I use sync groups with a walk and stop animation? I try to make a smooth and accurate transition from walk to idle via stop animation, but sync groups work quite weirdly. From your experience, when do you usually use sync groups?
Hi! Thank you for your comment! You can use sync groups in a wide variety of situations, as long as it is to synchronize specific events. The most common event is footsteps, to synchronize loops (walk and run for instance) or to avoid foot sliding when blending turns in place of different angles, or have nice and smooth transitions (start to walk, walk to stop). It's very broad. What kind of problem are you experiencing?
@@MattCourtoisAnim I have a weird glitch when there's a transition from walk cycle to stop animation. Looks like character's stop and walk animations aren't synchronized. Basically, the character's foot is on the ground, and then it's time for stop animation, so it's supposed to look like the character makes the left step and goes to idle, but in my case, I have second right and only then left step and transition to idle. I'm using Kubold's movement animset pro.
@@MattCourtoisAnim Also, how do you use sync markers with stop animations? I have 2 versions of stop anim when the right foot is up and when the left one is up, but I have no idea how to setup markers.
@@nevergonna sync markers will only allwo you to match the current foot phase to avoid bad blending, but won't help you to pick either of the stops. This is a bit more advanced, and you could use a Blend Pose by Bool do to this, provided your loop animation indicates which foot is currently moving.
@@MattCourtoisAnim Thats exactly what I did. Idk why, but when I disabled sync for stop animation, nothing changed - the same double step, which is caused by blending. Looks like sync doesnt work at all for some reason
If you’re blending from an idle to a walk and there are no steps in the idle, then what do you do? I’m trying to use blending with acceleration for a mech but the feet move really rapidly when transitioning from idle into the walk cycle. I thought sync groups might fix it but both the feet are just planted in the idle anim.
Yeah that makes sense, because the origin animation (the idle) doesn't provide any steps cycle information since it's static. You have two options: craft start animations, or start your walk cycle with the same foot forward as your idle. The latter will never be ideal, but it will save you time and data
@@MattCourtoisAnim Hi, I am with the same question Yes, I tried that - the walking cycle starts with the same leg, in idle inactive position (I don't have another animation to blend or transition) So what does unreal do plays as he wants - no logic - starts with whichever foot he wants, and I'm sure there are some transition or blending options somewhere... but I'll have to look.. UE is mixing them random...even i tried this variant, maybe I'm missing something.... somewhere
@@MattCourtoisAnim Wow!! Now my character is walking on solid ground and not sliding on thin ice. Huge upgrade in the locomotion quality. Thanks for the quick reply, see ya
Are you using only one stop animation? If you are, what could be happening is that there isn't enough data in it to cover all possible cases. If you want to use only one stop animation, it will have to contain a full loop cycle before it starts to decelerate so that the engine can start at the proper time to phase match. The downside is that the animation will last longer if you trigger the stop early in the loop. To address that, I would recommend to have two stop animations: one from each leg (left passover, right passover). You wouldn't necessarily have to use syncgroups then, since there cannot be any drastic offset between your poses. Let me know if that makes sense.

Hello, can this be applied to the animations within a blendspace? Thanks!
Absolutely! You just need to make sure all the animations within the blend space have sync markers, and then you set the group on the blendspace node
@@MattCourtoisAnim Wow!! Now my character is walking on solid ground and not sliding on thin ice. Huge upgrade in the locomotion quality. Thanks for the quick reply, see ya
is this work correctly as well if one of the animations has -1 scale reversed ?
Never tried that, but based on how the mechanic is built, it should. The events will be raised one after the other anyway.
Hmm, enabling the sync groups made my stop animation start looking really jerky and popping some of the time.
